Suzetrigine
Suzetrigine, sold under the brand name Journavx, is a medication used for pain management. It is a non-opioid, small-molecule analgesic that works as a selective inhibitor of Nav1.8-dependent pain-signaling pathways in the peripheral nervous system. It is not addictive. Suzetrigine is taken by mouth. The most common adverse reactions include itching, muscle spasms, increased blood level of creatine kinase, and rash. Suzetrigine was developed by Vertex Pharmaceuticals. It was approved for medical use in the United States in January 2025. Suzetrigine is the first medication to be approved by the US Food and Drug Administration (FDA) in this class of medicines. Medical uses Suzetrigine is indicated for the treatment of moderate to severe acute pain in adults. Efficacy In clinical studies conducted through 2024, suzetrigine reduced pain typically from seven to four on the standard numerical scale used to rate pain. This pain relief matched a combination of hydrocodone a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
By Mouth
Oral administration is a route of administration whereby a substance is taken through the Human mouth, mouth, swallowed, and then processed via the digestive system. This is a common route of administration for many medications. Oral administration can be easier and less painful than other routes of administration, such as Injection (medicine), injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Channel Blocker
Sodium channel blockers are drugs which impair the conduction of sodium ions (Na+) through sodium channels. Extracellular The following naturally-produced substances block sodium channels by binding to and occluding the extracellular pore opening of the channel: * Alkaloids: ** Saxitoxin (STX) ** Neosaxitoxin (NSTX) ** Tetrodotoxin (TTX) Intracellular Drugs which block sodium channels by blocking from the intracellular side of the channel include: * Local anesthetics: ''lidocaine'' * Class I antiarrhythmic agents * Various anticonvulsants: ''phenytoin, oxcarbazepine (derivative of carbamazepine)'' Unknown mechanism * Calcium has been shown to block sodium channels which explains the effects of hypercalcemia and hypocalcemia. * Lamotrigine is known to block sodium channels but it is not known whether it is extracellular or intracellular. * Cannabidiol (CBD) has been shown to cause inhibitory effects on sodium currents. This voltage-dependent inhibition is non-selective in natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analgesic
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, recent research has suggested that classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants may be considered as an alternative. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing to the substantial risks and high chances of overdose, misuse, and addiction in the absence of medical supervision. Etymology The word ''analgesic'' derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
